The frame F as disclosed in 'Figures 1to 5,`inolusive, and Figure 9"com prises a pair of upwardly vconverging leg members l 2 which terminatein an eye l or Aloop 3, the purpose for which willbe herebeing disposed about 'the portion 12' ofthe Figure 3 is a side elevation of the frame` leg 1 kand the portion 13 of the legf2; thesey relation to each other and, if desired, soldered oas to form a,l relativelyV rigid structure.

" f The loop `@maybe secured to the intermediateportions 12 `and 13 of the leg `members 1 n j and 2, respectively,` Vin any desired manner as f by Soldering, welding or the like, soas to prevent vertical movement of the upper pen wiper supportingelement 9)'on the frame F'. The legmember 1 attlelower end thereof is prefi erably bent kupwardly, as at '10, and this upwardly bent Yportion 410 continued forwardly `in a' horizontal extensionk 1l whichiis odset upfreine F. ..4Preferably, the leg members 1 and-;-

wardly from the lower end of the leg member 1 and the extension 11 terminates in a downwardly extending portion 7, the end of'which is adapted to engage a table or the like so as to cooperate with the lower end in supporting the leg member 1 in substantially vertical position. `In like manner, the leg 2 Aof the rame aF isV provided withf av similarlywiset. portion 11 which at the forward end thereof terminates in a depending leg 8 which leg S i cooperates with :thefleg'members 11, 2. andi im supporting the frame F in upright position.y

These extensions 11 and 11 of the yleg-mehr#"- be'rs l and 2, respectively, constitute ,1ower pen wiper supportingl elements which cooplf elment. 9 in supportingthe ,wiper-86911 the so as to provide aJ second lower wiper supporting element 22, the end of the wiper supporting element 22 being bent downwardl as at 23, so as to provide a leg member whic coopcrates with the horizontal portions 17 and 21 in supporting they leg member 1 in substanl tially vertically disposed, position.
